Secondly, it is relatively easy to derive a Peterken Stand Typefrom simple fieldwork whereas it is extremely time consumingto try to derive an NVC community from limited species lists.Moreover, the results may be open to question.Our method may give a biased result in that the UplandOakwoods, which appear to be so dominant, actually includeconsiderable areas of LMD. On the other hand, the use ofPeterken Stand Types has allowed us to produce results that aretransparent. That is, the allocation to PHT follows a clear andsimple method where the PHT usually shows a directcorrespondence to the original classification.The problem with this approach is that it is known that: ‘Thediversity which we perceive in vegetation types is affected by themethod we use … (and) … it is therefore useful to use them incombination (Jeanette Hall, JNCC Report No 272, p24).SummaryDefinitely is: Peterken Stand Type 6A or 6B.Overall AssessmentAverageProbably is: Inferred to be Peterken Stand Type 6A or 6B.CommentsThe map of this PHT for Cornwall probably gives a fairrepresentation of its distribution, but it does include woodlandswhich may better be regarded as Lowland Mixed Deciduous.Appendix 4 - Information Relating to Priority Habitat TypesCounty Wildlife Sites Criteria
